Application filed July 30, 1917.

To all whom it may concern:

Be it known that I, SHANNON L. VANALST, a subject of the King of GreatBritain, residing at Doughty, in the Province of British Columbia andDominion of Canada, have invented certain new and useful lmprovements inPencil-Sharpeners, of which the following is a specification.

This invention relates to pencil sharpeners of that type including ahollow conical rotary cutter into which the pencil is inserted to besharpened by the blade of the cutter.

The object of the invention is to provide a simply constructed andefiicient device of this character which may be mounted upon anysuitable support and readily assembled or disassembled when desired.

Another object is to improve and simplify pencil sharpeners of this typeso as to be re* liable and eflicient in use and in which the point ofthe pencil is protected while being sharpened and all possibility of itsbecoming broken while in the sharpener is prevented.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 represents a front elevation ofthis improved sharpener shown applied,

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1,

Fig. 3 is a similar view taken on the line 33 of Fig. 1, and

Fig. l is a central longitudinal section taken on the line l-t of Fig.2.

In the embodiment illustrated, the pencil sharpener constituting thisinvention comprises a pair of supporting brackets 1 and 2 which are hereshown in the form of substantially triangular plates having laterallyextending apertured ears 3 for the passage of the fastening elementswhich are designed to connect the brackets to the wall of a room or to adesk or to any other suitable support. These brackets are spaced apart asuitable distance to receive between them and Specification of LettersPatent.

the support a shaving receiving receptacle 4 which is here shownsemi-cylindrical in cross section, being provided at its opposite endswith upstanding lugs 5 having downwardly opening slots 6 therein whichare adapted to hook over studs 7 projecting laterally from the innerfaces of the brackets 1 and 2 as is shown clearly in Figs. 1, 3 and a.

The upper edges of the brackets 1 and 2 are provided with bearings whichare here shown in the form of recesses 8 and 9 dis posed in alinementwith each other when the brackets are mounted in operative position asshown in the drawings, the recess 8 in bracket 1 being larger than therecess 9 in bracket :2 for a purpose presently to be described.

The sharpener proper comprises a onepiece cutter in the form of a hollowsheet metal conical body 10 which is provided in one wall thereof with alongitudinally extending slot 11 in which is mounted a cutting blade 12which extends inwardly into the member 10 in the path of the pencil tobe sharpened. This conical body 10 is provided at its larger end with anannular closure provided with a tubular extension 13 having a flaredmouth 1% and which is designed to form a guide for the entrance of apencil to be sharpened.

The tapered smaller end of the conical body 10 is also provided with atubular extension 15 which communicates with the interior of the bodyand one end of which is designed to form a protector for the point P ofthe pencil P being sharpened as is shown clearly in Fig. 1, theextension being in alinement with said point so that no obstruction willbe offered such as would break the point. The outer end of thisextension is designed to receive shaft 16 which rests in 4 is engagedwith the studs 7 of said brackets and the sharpener proper is mounted inthe recesses 8 and 9. The handle 17 is then engaged with shaft end 18and the device is ready for use. The pencil P is then inserted throughthe flared mouth 14: of the tubular extension 13 and projected inwardlyinto the body 10 as far as it will go, and when in this position thepencil is held in one hand of the operator and the crank handle 17 isengaged by his other hand and thereby rotated relatively to the pencil,causing the cutting blade 12 to sharpen the point thereof. After thepoint has been sharpened it may be Withdrawn from the sharpener and thedevice is ready for the next use.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages ofthe construction and of themethod of operation will be readily apparent to those skilled in the artto Which the invention appertains and WhileI have described theprinciple 01": operation of the invention together with the device whichI now consider to be the best embodiment thereof,- I desire to have itunderstood that the device shown is merely illustrative andthat suchchanges may be made as are Within the scope of the claimed invention.

I claim In a pencil sharpener, the combination of a pair of plateshaving apertured attaching ears, and provided in their upper edges withsemi-circular recesses to form bearings, one being larger than theother, a one-piece sheet metal pencil holder and cutter comprising ahollow cone-shaped head carrying a longitudinally extending blade in oneside wall, said head merging at its smaller end into a tubular point andhandle receiving extension projecting longitudinally therefrom andadapted to rest in the smaller bearing, the larger end of saidvheadhaving an annular closure with a tubular pencil support extending fromthe center thereof and flared at its outer end, a handle fitted in theouter end of said first-mentionedtubular extension, and a receptacleremovably supported by said plates below. said sharpener.

In testimony whereof I affix my signature in presence oftwo Witnesses.
